As evidenced by many comments here and elsewhere, systemd is *not* a relatively useless change, most people welcome it because it's easier to configure, more reliable and more featureful than what came before it. So please stop spreading this kind of FUD. Systemd makes life easier for most people, not harder, which is why most significant distros adopted it by now.
And besides, most systems don't use SysVinit either, and even those who do often bear no resemblance to each other as pretty much everything is done by system-specific scripts. The introduction of systemd actually led to an *increase* in uniformity as distros share most of the configuration files.
